CHANGES FOR VERSION 6.20.1<\/strong> (as compared to 6.20.0)<\/p>\n

\n
1. Batch: DataImportASCII command allows to automate imports via batch. The parameter is file name to be imported. The importer uses file extension to determine format file used, so if you are importing File.aqh then aqh.format definition file will be used\n
2. Default for time compression timestamping changed to recommended value, i.e. 'start time of interval'\n
3. Plugin API: added GetExtraDataEx to support pad&align (see Release Notes)\n<\/ol>\n

   CHANGES FOR VERSION 6.20.0<\/strong> (as compared to 6.19.0)<\/p>\n

   \n
   1. AFL: new function GetExtraDataForeign - the same as GetExtraData but works with user-specified ticker instead of current one\n
   2. AFL: ShellExecute supports \"runbatch\" command. After running batch batch and analysis windows that were opened by batch are automatically closed\n
   3. Batch: new command DataPluginCmd - calls data plugin DataPluginCmd function (if it is exported from your data DLL) - allows custom actions to be peformed by the plugin from the batch (like maintenance)\n
   4. Batch: new command ExecuteAndWait - allows to execute external program and wait for its completion (allows among other things launching AmiQuote download and waiting until it is complete)\n
   5. New Analysis: changed forced refresh frequency of result list to every 250ms when analysis is in progress (since 6.16 when messaging system has changed it was refreshed \"on idle\")\n
   6. New Analysis: when user specified symbol with NO quotes at all as a reference symbol AND used \"last N days\" range AND used Exploration then it would lead to crash. Protection implemented against this scenario.\n
   7. OLE: AnalysisDoc.Export supports now extra (optional) parameter WhatToExport and it allows now to export not only result list but also walkforward tab Analysis.Export(\"file\", 1 );\n
   8. UI: In 64 bit version File Dialog was not resizable due to differences in Microsoft runtime. Now it is made resizable.\n<\/ol>\n

      9. AFL: updated text of Error 62 message to list newly supported sequence %s\n
      10. AFL: variable period Sum() now returns NULL if range is greater than current bar index (previously returned partial sum)\n
      11. Analysis: WalkForward settings including IS\/OS dates are no longer global, they are now per-project and saved in APX file\n
      12. ASCII importer: added $RAWCLOSE2AUX1 and $RAWCLOSE2AUX2 commands that allow to put raw close into aux1\/aux2 fields when using ADJCLOSE in 'close' field\n
      13. Changed wording to \"Free upgrade period expired.\" (from \"License expired\")\n
      14. Date\/Time fields in XML files now use ISO format always (not regional format), for better file exchangability accross regions\n
      15. Debugger: Watch window: added ability to display values of static variables in watch window - just append '$' (dollar) prefix before static variable name\n
      16. Default report chart dimensions (new instals) increased to 800x480px\n

              CHANGES FOR VERSION 6.17.0<\/strong> (as compared to 6.16.0)<\/p>\n

              \n
              1. New Batch processor - allows to define sequences of scans\/explorations\/backtests\/optimizations using different project files that are then run automatically. Detailed instructions on how to use Batch window are here http:\/\/www.amibroker.com\/guide\/h_batch.html<\/a>\n
              2. AFL: Changed default number formatting string from \"%g\" to \"%.7g\" (so 7 significant digits are now displayed instead of 6)\n
              3. AFL: new function GetFnDataForeign( \"field\", \"symbol\" ) - the same as GetFnData but retrieves non-current symbol's data\n

                  \n
                  1. New Analysis: implemented entirely new inter-thread communication method that does not strain main thread message queue. This gives tremendous improvement in responsivity of UI when Analysis is running\n
                  2. New Analysis: removed forced message pumping when AFL finished as it was causing issues with proper MDI tab refreshes in Windows 10 while Analysis was running\n
                  3. New Analysis: UI: added an option to keep using existing AFL file on opening APX project instead of asking the user what to do when differences are found between AFL file and content of APX project.\n
                  4. AFL: changed the way how custom-backtest reports \"stocknum\". Previously Status(\"stocknum\") was equal to zero on custom backtest phase and this may have caused parts that use if(Status(\"stocknum\")==0) to be excecuted during custom backtest phase. Now custom backtest reports stocknum equal -1.\n
                  5. AFL: DateTimeConvert supports now more formats, format = 6 - day, 7 - month, 8 - year, 9 - day of week, 10 - day of year, 11 - quarter (1..4)\n
                  6. Charts: as apparently single pixel geometric pens are 8 times slower than DC pen, the optimization has been implemented that uses DC single pixel pen instead of geometric pen when bar width is 1, giving 8x faster 1-pixel bar charts\n
                  7. Since 6.15 when $AUTOADD was set to 0 (zero), then symbols not existing in the database but present in the imported file were not logged into import.log as earlier. Fixed.\n
                  8. UI: when AM\/PM (12 hour format) was used in list views 12:00AM was interpreted as 12:00 (noon), instead of 00:00 (midnight). Fixed.\n
                  9. When backtesting Short only strategy and using backtestRegular mode and using HoldMinBars > 1, a disabled stop could trigger if it was enabled in previous backtest run. Fixed.\n
                  10. Support for Windows 98 and Millenium is dropped. If anybody needs that back please let us know (email to support)!\n<\/ol>\n

                      4. AFL: new modes added to DateTimeToStr() that use ISO regardless of regional settings mode = 3 (iso date and time YYYY-MM-DD HH:MM:SS) HH:MM:SS part is only included for non-EOD records, 4 (iso date only YYYY-MM-DD), 5 (iso time only HH:MM:SS)\n
                      5. AFL: NumToStr could crash if format parameter was greater than 127. Fixed. Now an error message is displayed when format parameter is too large\n
                      6. AFL: NumToStr now supports formatDateTimeISO\n
                      7. AFL: StDev function added 3rd argument \"Population = True\", when Population is True it calculates population based stdev, otherwise sample based\n
                      8. ASCII import: from version 6.11 importer always added new symbols even if $AUTOADD 0 was used. Fixed.\n
                      9. UI: Charts window - an attempt to rename a file or directory to something that already exists is now prevented and results in error message box.\n
                      10. UI: in 6.14 when New Analysis was switched to 'floating' mode, it could crash on attempt to run analysis. Fixed.\n
                      11. UI: Quote editor - in single-symbol mode \"ticker\" field sometimes was not updated. Fixed.\n
                      12. UI: Symbol->Quick Find menu command brings focus to Symbol's window search box. New installations use F3 key assignment for Quick Find. Old installations use old assignment (you can change F3 assignment in Tools->Customize->Keyboard)\n<\/ol>\n

                          2. AFL: PercentRank function now accepts variable period (range)\n
                          3. AFL: PriceVolDistribution crashed if startbar argument was negative. Fixed by implementing protection against negative bar indexes.\n
                          4. AFL: PriceVolDistribution sometimes produced some random values in 6.13. Fixed.\n
                          5. ASCII importer now supports microsecond resolution timestamps (HH:MM:SS.mmmuuu) where mmm - milliseconds 000..999, uuu - microseconds 000..999\n
                          6. New Analysis: new feature a PAUSE button to temporarily pause\/resume any running analysis. Note that already running threads are not interrupted, they are allowed to complete gracefully and then pause state is entered.\n

                          11. When broker.workspace file was corrupted or truncated, the file remained open which eventually prevented from writing it on close. Fixed.\n<\/ol>\n

                              CHANGES FOR VERSION 6.13.0<\/strong> (as compared to 6.12.0)<\/p>\n

                              \n
                              1. AFL Editor: calling SetForeign thousands of times followed by RestorePriceArrays() could cause exception during code verify when number of symbols exceeded cache size. Fixed.\n
                              2. AFL Editor: changes made in 6.11 to the way how automatic names for new formulas are assigned have been removed and replaced by new method that is faster and more reliable.\n

                                      2. AFL: MxFromString was slow on very large matrices (>100000 cells) due to poor performance of strtod function from Microsoft C runtime. Now MxFromString does not use it and is even 1000 times faster on 100K+ cell matrices (5ms vs 5second)\n
                                      3. ASCII importer can now be even 20 times faster when importing NEW (non existing) data that were oddly sorted (like for example in reverse order - descending dates instead of ascending).\n
                                      4. ASCII importer is now twice as fast when updating already existing quotes thanks to using in-house code instead of msvcrt functions.\n
                                      5. Charting: Fibonacci maximum user-definable level increased to 9000% (from 1000%)\n
                                      6. Idle processing is forced now every 125 ms (instead of 250ms) in Analysis window to update UI components more frequently under heavy CPU load\n
                                      7. Ruin stop is identified by Short(ruin) \/ Sell(ruin) instead of Short(6) \/ Sell(6)\n
                                      8. Startup splash screen is displayed a little sooner now and some pre-loading of editor components is done at start to save time to open editor later\n
                                      9. When there were thousands of files in \"Formulas\" folder opening editor for the first time could take some time. Now this time is significantly reduced.\n<\/ol>\n
